Sun(sm) Alert Notification
     * Sun Alert ID: 102117
     * Synopsis: Security Vulnerability in PC Netlink 2.0 "slsadmin" May
       Allow Files to be Opened Insecurely
     * Category: Security
     * Product: Solaris PC NetLink 2.0
     * BugIDs: 6215631

1. Impact

   A security vulnerability in the "/etc/init.d/slsadmin" script in PC
   NetLink 2.0 may allow files to be opened insecurely, which could allow
   an unprivileged local user the ability to write to the filesystem with
   the permissions of the user running "slsadmin." If "slsadmin" is
   run as "root," it may allow a local unprivileged user to gain elevated
   privileges on the system and run arbitrary commands.

2. Contributing Factors

   This issue can occur in the following release:

   SPARC Platform
     * PC NetLink 2.0 (for Solaris 7, 8 and 9) without patch 121332-01

    1. Solaris for x86 is not affected by this issue.
    2. Solaris 10 is not affected by this issue.
    3. PC NetLink 1.0, 1.1 and 1.2 are not affected by this issue.

    UNIX Systems Server

   To determine if the SUNWlzas package (for slsadmin) is installed on a
   system, the following command can be run:
    $ pkginfo -l SUNWlzas
      PKGINST:  SUNWlzas
         NAME:  Solaris (TM) PC NetLink Adm Srv
